Inhibition of Ehrlich Ascites Tumor Growth by Nucleoprotein. I. In Vivo Characterization and Presumptive Chemical Identification

A badly degraded preparation of herring-sperm deoxyribonucleic acid (DNA) prevented the development of Ehrlich ascites tumor in mice, though, in large doses, this substance appeared to be nontoxic. The protective ability of the DNA preparation was destroyed completely by proteolytic enzymes, but onl...
